Since there are so many itchy bug bites, we’ll evaluate several examples of bugs that cause hives. Then, we’ll list some preventive measures you can take against the bugs that make you itchy.
What Bugs Cause Hives?
Bugs can be a source of a lot of different types of skin rashes, and hives are just one of them. But what exactly causes hives? And how can you tell if your symptoms are caused by an insect bite or something else? Here’s what you need to know about this common skin rash.
What are hives?
Hives are red, raised bumps that appear on the skin. They can vary in size and shape, but most often they look like small red welts all over your body. The welts may itch or burn, and they can last from a few hours to several days, depending on what’s causing them.
What causes hives?
Hives are caused when your immune system reacts to something in your environment like an allergy trigger like pollen or pet dander by overproducing histamines in the bloodstream. Histamines cause blood vessels close to the surface of your skin to dilate (open wider), which leads to swelling and redness in those areas. That swelling causes the bumps we see as hives.
If you have allergies, then you’re probably familiar with this process already: Your body responds to allergens by releasing histamine.
Bugs can cause hives, but there are other causes as well.
Hives are red, itchy bumps on the skin that appear suddenly and may be accompanied by swelling, tingling, or warmth of the skin in the affected area. They’re also called urticaria, and they can range in severity from mild to life-threatening.
The most common cause of hives is an allergic reaction to something you’ve been exposed to (like pollen or pet dander), but other causes include medications like blood pressure pills or antibiotics.
Insect bites can also sometimes cause hives. Insects like mosquitoes, fleas, bedbugs, and ticks carry diseases that can cause a reaction in people who have been bitten by them and these reactions often manifest themselves as hives.
The good news is that most cases of insect bites eventually resolve on their own without any treatment necessary but if your hives keep coming back after a few days, see your doctor for evaluation.
